Known Issues
------------
Viper VLB: This driver does NOT currently support the Viper VLB.
Support for this card will be added in a future release
of the driver.
ALL CARDS: On installing the driver you may encounter scrambled or
corrupted toolbars or menu buttons. To resolve this issue, open the
"Display Properties" screen. Click on the "Diamond Viper" tab. Click
on the "Driver Options" button. Remove the check mark from the
"Host BitBlt" option in the "Accelerate GDI" section. Note: If the
problem persists, disable the other options under "Accelerate GDI"
until the problem stops. This problem is being investigated.
Viper SE VLB 2MB with BrookTree 485 DAC: Windows displays
black screen when using 800x600x32bpp.
Viper SE VLB 2MB with BrookTree 485 DAC: Random screen corruption
in Adobe Illustrator 4.10.
Windows 95 VDD bug: On VLB and some early PCI systems the BIOS setup
needs to have Shadow BIOS for the VGA Adapter region (C0000~C7FFF) set
to Write Protect, if available. This problem is noticeable if you open
a DOS session Full-Screen then press <ALT><ENTER> to return to Windows
and again <ALT><ENTER> to return to DOS Full-Screen. If the system then
locks-up or gives a blue screen fatal-error message this means that the
card's VGA BIOS has been overwritten and you must either enable Shadow
Write Protect, or altogether disable Video ROM-BIOS Shadowing. This
problem is caused by the Windows95 VDD and cannot be corrected in
future drivers.
ALL PCI: Color palette shift in Mech Warrior 2 (Pentium Processor
Edition) when game starts.
Known Limitations
-----------------
Viper SE 2mb with BrookTree 485 DAC: No 24 bit color option. This is a
limitation of the hardware.
Issues Addressed and Features Added
-----------------------------------
DirectDraw: The driver now provides hardware acceleration and support
for Microsoft's DirectDraw API.
Acceleration: Screen to Screen BitBlt's, Memory to Screen, Solid
Brushs, Patterned Brushes, Quads and TextBlts are now supported and
accelerated wherever possible.
WeitekCPLX: The control panel has been extended to work with the new
Microsoft DisplayCard Driver interface method.
DPMS: Was not asserting blanked video during shutdown (DPMS Level-3)
and thereby not fully switching off the monitor.
